Bigs: More than 150 (how many more is unknown - that's where the filter caps out) - we pay in USD (not AUD)
Indeed, 150 is the filter limit thats why I edited my earlier post. The regional pricing on a majority of games from big publishers on Steam is not favorable for AU judging by most of the publishers on that list and the ones you mentioned.
mrkgnao: Thanks for the link. It seems that that engine does not return more than 150 results.
Still, it does appear there are a lot more games on Steam that are more expensive in AU than cheaper. Thanks.
No problem, Steamprices is a good resource for checking pricing for all the different regions though it would have been more helpful if the search filter wasn't capped. They could definitely learn a thing or two from MaGog in that regard. ;)
